There are a number of differences between the US and all the other countries which may explain the costs. For example - Malpractice insurance costs in the US are much higher, the salaries for doctors are higher, the cost of their education is higher, living expenses can be higher... And because it is privatized - in the UK for example, the government can negotiate fees to bring down costs (for drugs, services etc). They can set prescribing guidelines so physicians don't just prescribe what they want and they can set treatment protocols and budgets so the physicians don't order unnecessary scans. All this brings down the overall costs.
